gniibe claimed T4502: keys added via gpg-agent's ssh-agent interface are stored in private-keys-v1.d/ with a trailing null byte.

I located the bug in agent/command-ssh.c.
Our practice is two calls of gcry_sexp_sprint; One to determine the length including last NUL byte, and another to actually fills the buffer.
The first call return +1 for NUL byte.
The second call fills NUL at the end, but returns +0 length (length sans last NUL).

ctubbsii added a comment to T4522: gpg-agent's EXPORT_KEY command does not tell its pinentry SETKEYINFO , preventing use of external passphrase cache .

I spent a lot of time trying to figure out how to automate the interface between my preferred password store (gnome-keyring, via libsecret), but with the loopback pinentry mode changes in gpg 2.1, it is much harder (if not impossible) to do. Having passphrase caching is the only thing preventing me from choosing a weaker passphrase on my gpg keyring.

Disallowing passphrase caching is likely to have the unintended consequence of users choosing weaker passphrases that are more easily memorized and/or typed. Caching should be permitted, IMO. This puts more decisions about passphrase management into the control of the user.

That is on purpose. Exporting of a secret key should in theory not be possible at all via gpg. In practice we need a way to export a key, but that should be the exception and thus we do not want any caches for passphrases to have an effect.

That's my badness. In wait_child_thread, assuan_release may cause thread context switch to agent_reset_scd which accesses scd_local_list; This access should be serialized.
And... in start_scd, calling unlock_scd should be after unlocking start_scd_lock.

Not a bug :-). I should have read my own docs before starting a long debug session. The things is that the auto expanding of the secmem area is only done for xmalloc_secure and the internal MPI allocation functions. It is not dne for any memory which is allocated with xtrymalloc becuase those properly return an error to the caller. The idea is that if the caller wants to get an error back he has also the assurance that them memory is allocated in the non-swappable memory (i.e. not in the expanded parts of the secmem).

gniibe added a comment to T4255: gpg-agent: "<gcrypt> Cannot allocate memory" with 10 threads decrypting OpenPGP.

For my case, with $GNUPGHOME/gpg-agent.conf having debug-all, I observed that rsa_decrypt failes with 'Cannot allocate memory', after debug output of 'res'.
Reading libgcrypt/cipher/rsa.c, it is line 1439, where it calls sexp_build (MPI of PLAIN into SEXP of R_PLAIN).
I think that it does indeed memory failure here.
Having "auto-expand-secmem" in gpg-agent.conf, it goes well.

I can easily replicate this; it is a problem somewhere in the secure memory code of Libgcrypt.

mjb added a comment to T4273: agent: Request insertion of smartcard when no card present.

..... And now after looking into this a bit deeper after attempting to build gpg-agent for windows, it appears that this is a bit deeper than the logic above (which is actually sound, when I read it for the second time)
